Biography

Anthony "Tony" Chavez was a longtime resident of 37th Street in the "Denver Steels" neighborhood of Los Alamos, New Mexico. He worked at Los Alamos National Laboratory until his retirement around 2017. His specific role, job title, and research area at LANL have never been publicly disclosed — news reports refer to him only as "a former employee" or "a former worker" at the laboratory.

Despite being 78 at the time of his disappearance, Chavez was described as "very fit and slender, healthy and clearheaded." He was 5'6" tall and approximately 135 pounds, bald, and wore glasses. Friends described him as "somewhat of a loner" but noted he "wasn't lonely and made friends everywhere."

Disappearance

Last Known Movements

  • May 4, 2025: Chavez was last seen leaving his home on 37th Street in Los Alamos on foot
  • Evening of May 5: Last landline telephone calls were made from his home
  • ~May 5-8: Banking activity ceased around this time
  • May 8, 2025: Reported missing to the Los Alamos Police Department (Case #2025-0254)

What Was Left Behind

  • His car remained in the driveway
  • His wallet, keys, and cigarettes were left on the living room table
  • No evidence of a scuffle or blood was found in the home
  • He did not carry a cell phone — investigators could only track his landline activity

The investigation was led by Detective Ladislas Szabo of the Los Alamos Police Department. Search efforts included:

  • Thorough searches of known residences
  • Hiking local trails
  • Distributing flyers to businesses throughout Los Alamos
  • Reviewing hours of surveillance footage
  • Following up on every tip received
  • On June 18, 2025, volunteers with trained cadaver-detection dogs from the Sandia Search Dogs and Mountain Canine Corps searched his home, his nearby sister's house, and Pueblo Canyon bench trails — all without result

Unverified sightings were reported at the Albuquerque train station and airport (reportedly with baggage), but these did not lead to anything concrete.

Current Status

As of early 2026, the Los Alamos Police Department reports the search "is still ongoing and no new information in the case has emerged, nearly one year later." Anthony Chavez has never been found.

Connection to Los Alamos National Laboratory

Los Alamos National Laboratory is one of the most sensitive facilities in the United States:

  • Founded in 1943 as the secret laboratory for the Manhattan Project
  • Designs and maintains the United States' nuclear weapons stockpile
  • Conducts classified research across nuclear physics, materials science, computational science, and national security
  • Operates under the oversight of the Department of Energy/National Nuclear Security Administration
  • Has historically been connected to some of the most compartmented programs in the U.S. government

Chavez's specific role at LANL is unknown. Whether his work touched on any research relevant to UAP physics — advanced materials, exotic energy, plasma physics — cannot be determined from public sources.

Connection to Melissa Casias

Just seven to eight weeks after Chavez vanished, Melissa Casias — an administrative assistant at Los Alamos National Laboratory with security clearance for sensitive data — also disappeared.

  • June 26, 2025: Casias drove her husband Mark to LANL that morning, forgot her badge, and returned home to work remotely. She was last seen around 2:18 PM walking eastbound on NM-518 from Talpa, New Mexico, approximately three miles from her home.
  • She left without her wallet, phone, or keys — eerily similar to Chavez
  • Her phones were later found at home with their data completely wiped after someone performed a factory reset
  • She held security clearance for sensitive data at LANL
  • She has never been found
  • New Mexico State Police reported "no breakthroughs" — neither ruling out foul play nor the possibility she left of her own accord
  • NBC Dateline covered her case in its "Missing in America" segment

The parallels between Chavez and Casias are striking:

  • Both connected to Los Alamos National Laboratory
  • Both vanished from the same geographic area (Los Alamos/Taos, New Mexico)
  • Both left personal belongings behind (wallet, keys, phone)
  • Both vanished within weeks of each other
  • Neither has been found

Connection to the 2024-2026 Scientist Death Pattern

Chavez and Casias are part of a documented pattern of eight or more deaths and disappearances involving scientists and defense-connected personnel between July 2024 and early 2026:

  1. Frank Maiwald (NASA JPL) — died July 4, 2024, cause undisclosed, no autopsy
  2. Anthony Chavez (Los Alamos) — vanished May 4, 2025, never found
  3. Monica Jacinto Reza (NASA JPL) — vanished June 22, 2025, never found
  4. Melissa Casias (Los Alamos) — vanished June 26, 2025, phones wiped, never found
  5. Nuno Loureiro (MIT) — shot December 2025
  6. Jason Thomas (Novartis/DoD) — vanished December 2025, body found March 2026
  7. Carl Grillmair (Caltech/IPAC) — shot February 2026
  8. William McCasland (AFRL) — vanished February 2026, never found

The New Mexico Cluster

Three of the missing individuals vanished from the New Mexico defense corridor — the densest concentration of nuclear and aerospace research facilities in the United States:

  • Anthony Chavez — Los Alamos, May 2025
  • Melissa Casias — Taos/Los Alamos, June 2025
  • William McCasland — Albuquerque, February 2026

McCasland, who commanded the Air Force Research Laboratory and served as Director of Special Programs at the Pentagon, reportedly "worked closely with LANL on national security projects at Kirtland Air Force Base." The geographic and institutional proximity of these three disappearances in the New Mexico defense corridor is notable.

Key Quotes

"It is very much out of character or circumstance for him to be out of touch with his family or friends for more than a day." — Carl Buckland, friend of Chavez, Boomtown Los Alamos, 2025

"Something dark is going on. I know these scientists and researchers. They have testified. We've got to get to the bottom of it." — Rep. Tim Burchett (R-TN), regarding the broader pattern of scientist deaths and disappearances, Daily Mail, March 2026

The Counterargument

  • Chavez was 78 years old; elderly adults sometimes wander due to undiagnosed cognitive issues, though friends described him as "healthy and clearheaded"
  • His specific role at LANL is unknown — he may not have held a position involving classified research
  • He had been retired from LANL for approximately eight years at the time of his disappearance
  • The unverified sightings at the Albuquerque train station and airport could suggest he left voluntarily
  • The connection to Casias may be coincidental — Los Alamos is a small community where many residents have LANL connections
  • Law enforcement has not linked his case to the other scientist deaths or disappearances
  • William McCasland — Retired AFRL commander who vanished from Albuquerque seven months after Chavez; part of the New Mexico cluster
  • Monica Jacinto Reza — JPL aerospace engineer who vanished seven weeks after Chavez; her Mondaloy research was funded by AFRL
  • Frank Maiwald — JPL scientist who died 10 months before Chavez vanished; first case in the 2024-2026 pattern
  • Nuno Loureiro — MIT plasma physicist shot seven months after Chavez vanished; part of the broader pattern
